Since the newest updates having issues with one particular amp always disconnecting. Never had that problem before.
Update. In regards to one of my av receivers always disconnecting I really meant not being listed in the app itself. I figured out after reading yamaha troubleshooting my amp was going to sleep so had to turn on sleep setting in the network settings. Now it can see it all the time. Pats to read instructions. Great app would recommend it to yamaha owners.
